Motorcycles have headlights and tail and brake lights and travel at the same speeds cars to. Bicycles arent typically ridden on dark country roads at night and most bikes have reflectors. Bicycles are also smaller and can usually stay closer to the side of the road unlike buggies.
Bicycles here are required to have a light on the front and a taillight on the back, just like cars. I have noticed some wearing yellow reflective vests at night. Good idea.
